The Company - AI systems are only as reliable as the data and feedback loops behind them. We’re partnering with a profitable, globally-used technology company building infrastructure that helps global organisations develop more reliable, trustworthy AI systems. Their platform supports teams working across research, healthcare, and enterprise environments - where accuracy, integrity, and real-world performance genuinely matter. The business has been operating successfully for over a decade and is now scaling rapidly due to accelerating demand in AI. With strong product-market fit and significant growth ahead, they’re investing heavily in senior engineering talent to shape the next phase of the platform.
The Role - You’ll join a senior, product-focused engineering team working in small high performance teams building high-scale backend systems that sit at the core of the company’s platform. This is a backend-first role (Python ≈70%) with meaningful influence across system design, architecture, and product direction. You’ll operate with real ownership - balancing delivery speed, scalability, and long-term maintainability - while contributing to a platform that underpins critical AI-driven applications globally.
What You’ll Be Doing -
- Designing and owning backend services in Python (Django / FastAPI)
- Building scalable APIs and workflows supporting global usage
- Improving reliability, performance, and developer experience
- Working closely with Product and Design to shape features end-to-end
- Contributing across the stack when useful (TypeScript exposure)
- Helping evolve engineering standards as the team scales
This is a pragmatic, fast-moving Product Engineering centric environment - but with a strong emphasis on thoughtful engineering.
Tech Stack -
- Python (Django core)
- FastAPI (in parts)
- PostgreSQL
- TypeScript / Vue.js
- AWS
- Modern CI/CD practices
What They’re Looking For -
- 4–6+ years of professional software engineering experience
- Strong production-grade Python
- Experience building scalable backend systems
- Comfort operating with ambiguity and ownership
- Product mindset - thinking beyond implementation
- Clear communicator, collaborative by nature
- Experience in startup or scale-up environments preferred
- No degree requirements
- Exposure to AI systems, research platforms, or data-intensive products is a bonus — not required.
Interview Process -
- 30-minute intro (Engineering & Talent)
- 60-minute collaborative Python pairing session
- Product & architecture discussion
- Final conversation with senior leadership
Structured, respectful, and focused on real-world thinking.
Why Join -
- Globally used platform with strong product-market fit
- Direct impact on how modern AI-enabled systems perform in the real world
- Senior hiring bar - high quality, low ego
- Fully remote within the UK, with a London office
- Engineering team scaling from ~60 → 100+
- £80–100k base + bonus + equity
- Strong benefits package
